The Gainward GTX 770 Phantom certainly is an impressive graphics card that not only looks cool, but also runs cool. It is also very quiet, making less noise than most case fans - it certainly wasn’t heard over anything else in our test system. While the Gainward GTX 770 Phantom does provide more performance when compared to a standard GTX 770, as is often the case with factory overclocking the gains are not huge. Still with an average of 5% more performance in the ten games that we tested with, the gains are worth it.
